Binding of RSA soft token to a specific device

Our client wants to bind a specific laptop to a RSA soft token to ensure that only authorized user and laptop can use a specific RSA soft token.

We have looked on using the Device Attributes DeviceSerialNumber field to restrict the installation of a token to a device platform or to a specific device. Do we have a generator for DeviceSerialNumber? How can this be obtain other than installing a RSA SecurID Software Token Application?

On Windows...It is unknowable beforehand, or the entire concept of using the device specific number as a binding mechanism would not be useful. WMIC BIOS GET SERIALNUMBER has zero to do with RSA Software Token binding serial number.
